The circular buffer is provided with a cursor pointer for indicating the position of the buffer where a recognized character is loaded. Every time a character is recognized, its character code is loaded at the buffer indicated by the content of the cursor pointer and thereafter, the content of the cursor pointer is incremented by 1. At least an input buffer after the buffer indicated by the content of the cursor pointer, where a handwritten character is next written, is cleared. Then, the content of the character input buffer is displayed on a display. | |
